CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 357,451, dated February8, 1887.

Application filed May 10, 1886. Serial No. 201,6ti6. (No model.) I

To all whom, it may concern.-

Be it known that I, ROBERT*BIGNEY, of Oopleston, in the county ofLambton and Province of Ontario, Canada, have invented a new and usefulImprovement in Car-Couplers,

which improvement is fully set forth in the following specification andaccompanying drawings, in which- Figure 1 is afront View of an ordinaryfreight- Fig. 2 is a .perspective view of the same, and Fig.3 anenlarged perspective view of'a section of the coupler detached. Fig. 4is a detail view, partly in plan and partly in section, showing how thespring operates the lever.

This invention relates to an improvement in car-couplers wherein Iprovide a draw-head provided at one side with a hook and at the oppositeside with a pair of laterally-disposed ears, within which is a leverpivoted thereto, having forwardly a hook and also a means for connectingthe ordinary coupling link and pin, and rearwardly a spring whichpresses the rearend of the arm outwardly against a camwheel, and ahorizontal shaft having lateral cranks, and also connecting with avertical shaft extending to the top of the car and provided with acrank, the said shaft having beveled wheels connecting with ahorizontalshaft, the device so disposed as to be in a position for connecting withan ordinary spring-coupler or an ordinary link-coupler, all of whichwill now be fully set forth.

In the accompanying drawings, A represents the forward end of anordinary box-car having thereon the coupler B, operating with-. in thekeeper 0. Forwardly the coupleris enlarged somewhat vertically, as at D,and has a hook, E, at oneside. On the opposite side from the hook E, Iprovide a pair of wings, F, one above the other, having centrally anopening, G, for the reception of the pin H. (Shown in Fig. 2.)

Between these wings F, Iprovide alever, I, provided at its forward endwith a hook, J, on the side corresponding with the hook E of thecoupler. The forward end of this lever also has an opening for thereception of the pin K, and a recess, L, for the reception of anordinary link, M, as shown in Fig. 2. Real-wardly this lever I has aspring, N, resting within the recess 0 of the coupler, and projectingforwardly and so disposed as to rest beneath the rearward end of thelever I, the object of the spring being to throw the hook toward theside of the car carrying the hook E, and thus have it in position toengage with the opposite coupler. The use and operation of the hooks Eand J are simply to engage with the corresponding books on the couplingof the opposite car.

Above the coupler I provide a horizontal cross-shaft, P, journaled tothe forward side of the car, having acam-wheel, Q, at the side sodispose d as to engage with a vertical pin, R, on the rear end of thelever I. The tension of the spring N is suchthat it will cause the pin Rof the lever I to press outwardly against the inclined face of the cam.The ends of the shaft I are provided with cranks S, so that the saidcranks may be rotated, while centrally I pro vide a vertical shaft, T,having a crank, U, at its upper end, near the top of the car,while itslower end has abevel-wheel,V, engaging with a corresponding bevel-wheel,V, on the hori- 7 5 zontal shaft P, so that the cam-wheel Q may berotated either from the side or top of the car, as desired. As the saidcam Qis rotated by the operation of either of the shafts P or T, itpresses against the pin R, and in connection with the spring N the leverB is movedlaterally on the pivotal pin H.

The hook E and the hook J of the lever I serve a double purpose, as willbe noticed, and also, in connection with these, the lever I beingprovided at its forward end with the recess L and pin K, it may readilybe connected with the ordinary coupling-link.

Having described my inventiomwhat I claim as new is 1. In a car-coupler,the draw-bar B, having the hook E, and oppositely a supplemental pivotallever having a hook-and-link connection operated by a cam-wheel andshaft, substantially as herein set forth.

2. The combination of the draw-bar B, having at one side a hook, E, andoppositely-disposed wings F, openings G, and pivotal pin H, with thelever I, and supplemental hook J, recess L, and pin R, having rearwardlythe spring rco N and cam Q on the horizontal shaft P, sub- In testimonythat I claim the foregoing I stantially as herein set forth. havehereunto set my hand, this 16th day of 10 3.
